I've attached your pre- and post-transition digital reports here. I don't remember exactly, but I think you might be able to attach files to your posts prior to the 5 post minimum.

It's not clear (even after all the discussions in here) if the 91XG would be a better choice for this location. I am also wondering about the Clearstream 4 , since the smaller the antenna the better it deals with the severe snow loads up here. It is not uncommon for a storm to leave 3 feet of snow on the horizontal portions of an antenna & it can take several days before it falls/melts off.
The XG91 may actually be better for you. It is light-weight yet sturdy and plays nice with other antennas on the same mast. The 4228 takes up a lot more vertical space and is much heavier. The Clearstream 4 doesn't really seem that much better because its elements have more surface area for snow and ice to cling to.

Are you using a pre-amp? If not, I'd recommend the CM 7777. Without a pre-amp, you're sacrificing an additional 5 to 10 dB of signal quality to the cable losses and tuner noise figure.

Cheers,
